We’ve published a geography lookup table to help you understand which local authority, ward or local health board a postcode is in. We’ve made this available as a result of demand from users wanting to use this information e.g. vaccination centres, to understand which local authority/local health board a person’s postcode belongs.
The table contains the names, descriptions, and identification codes of Welsh statistical geographies, from postcode through to local health board, and how they relate to each other.
The data is updated quarterly following a release by the Office for National Statistics (ONS).
The table can be found in our tools OpenDataWales and InfoBaseCymru.
